There are two Catilli in Roman legend:
- Catillus the Arcadian, son of Amphiaraus.
- Catillus, his son.
Catillus the Arcadian and his sons Catillus, Tiburtus and Coras escaped the slaughter at Thebes and arrived at the Aniene Plateau. They drove away the Sicilians who lived there and founded a city named Tibur (now Tivoli) in honor of Tiburtius.
